Actually, here is what the
Bonita Papers say about the two hairs (bearing in mind that this was written from notes taken early in the investigation):
The white blanket found with JonBenet’s body and the swabs of substances recovered during the autopsy were examined for semen. Serological studies did not find the presence of semen on any of these items. However, two hairs were recovered from the blanket. One of the hairs, identified as a Caucasian pubic hair, did not match samples from John, Patsy or John Andrew. A second hair, was also identified as human head hair several inches long, was also examined but no conclusions were reached as to the source.
The DNA samples extracted from the fingernails and the panties, and the two hairs were sent to CellMark Diagnostics, Inc. in Germantown, Maryland for further analysis.
This account does not mention here or later the results from CellMark’s testing, so I would guess it was written from notes taken before the results came back. I don’t know which of these two hairs was later reported to be an “ancillary” (or sometimes an “axillary”

hair. For me, it’s hard to imagine either of the two hairs described here as being from almost anyone’s forearm. If it is the one described as possibly a “
Caucasian pubic hair”, it would be unusual for it to be the type found on most people’s forearm. The other hair is described as a “
human head hair several inches long”, and again is unlikely to be typical of hairs found on anyone’s forearm.
Either way, with no more information than we have, I think it’s hard to put much weight into the meaning or implications of these two hairs.
